Step 5 : Find Your CB ( Cold Bug ) and CBB ( Cold Boot Bug ) Temperatures
If you ’ re not an experienced extreme overclocker we suggest you to spend the time to find the CB and CBB of your CPU . Once you find them you will be able to eliminate CB and CBB off of a list of issues that may be hindering your overclock . Cold Bug is the lowest temperature your CPU can operate at . Cold Boot Bug is the lowest temperature your CPU be at and still boot . From our experience with the 7th gen CPUs , we ’ ve seen that CB and CBB are very similar to the previous 6th gen CPUs . CBB is mostly CPU specific and it is approximately around -130C . Some CPUs may be able to boot at -120C and some at -135C . CB on all the CPUs we ’ ve tried are the same-you can go full pot ( -190C ).
Step 6 : Adjust Frequencies + Some Tips
• CPU frequencies range from 6.4 to 6.9 and maybe even higher for HWBOT Prime . Good CPUs can do 6700 + with around 1.8V . Some CPUs stop scaling at around 1.8-1.85V but some can go up to 1.9 +.
• Some good news-from our observations we ’ ve seen that average next-gen retail Intel CPUs can clock as high as engineering samples .
• Uncore uses CPU Vcore voltage . If you want to raise Uncore frequency you might want to raise CPU Vcore voltage . 6700 Mhz Uncore worked for us on SuperPi 32M .
• If you ’ re hitting lower frequencies ( i . e 6 Ghz ) make sure your CPU mounting is good .
• Compared to a Gaming 7 motherboard the same CPU could only clock up to 6.2 Ghz , when on Gaming SOC due to its extra voltage settings it was able to do 6.7 Ghz . We found no difference between the motherboards when doing standard overclocking on air or water .
Step 7 : Troubleshooting
Potential issue : previously stable frequencies are now unstable
Make sure you have a stable mount when you are overclocking . You will find that once you start to push high frequencies and volts that your paste may not work correctly and your CPU can become unstable at previously stable frequencies . The best way to OC is to use a staggered approach where you start with a 5 , 5.5 , 6 and 6.5 Ghz profiles with specific volts and temp ranges . If you crash at any stage , you probably " lost your mount ". Essentially your paste snapped and is not conducting heat properly between the CPU HS and CPU pot . One way you can detect this is with a delta probe ( keep one temperature probe on HS and second on CPU pot ).
